Rigid Portal Frame Steel Structure Workshop Construction Project

Experienced Design Rigid Portal Frame Steel Structure Workshop Construction Project

The Experienced Design Rigid Portal Frame Steel Structure Workshop Construction Project applies prefabricated steel to form a load-bearing structure. Generally, the load-bearing structure is called main frame, which are consisting of beam and column . The secondary steel bracing system normally includes tie bar, knee bracing,purlin, sag rod, column bracing, as well as horizontal bracing. Together with roof system, wall system, and floor system, they are conforming an entire steel structure building.

Compared with traditional concrete buildings, steel structure workshop applies steel plates or sectional steel instead of reinforced concrete, thus the workshop steel structure performs much higher strength, and better seismic resistance. Because of the components mostly being prefabricated in factories and assembled on-site, the construction period is greatly reduced. Due to the re-usability of steel, it can greatly reduce construction waste and become more environmentally friendly option.

Specification of the Portal Frame Steel Structure Workshop

Advantages of Steel Structure Workshop

1. Easy to assemble

The steel components arriving at the construction site are all prefabricated. During the construction process, the installation work needs to layout each structure and erect it according to the installation drawing.

The installation sequence of the steel workshop building is:

First, install the steel columns and column cross-bracing and install roof beams and roof horizontal bracing. Finally, installs the purlin and enclosure structure.

2. Reasonable cost:
The steel structure workshop building is light in weight, reducing the basic cost, and the construction speed is fast. It can be completed and put into production as soon as possible. The overall economic benefits are much better than that of the concrete structure

3. Simple construction, short construction period.
The production and installation of steel structure usually involve processing all required components in the factory and then transporting to the construction site to assemble. So the construction period is greatly shortened. A 4000 square meter building can be basically installed in only 40 days.

4. Energy-saving and environmentally friendly
The corrugated color steel sheet and sandwich panels used in the prefab steel structure workshop are all energy-saving materials. The steel structure also adopts dry construction during the construction process to avoid dust and environmental pollution caused by concrete construction.

Design Important Factors

1. Reasonable column spacing

Steel structure buildings mainly apply H-section steel columns and steel beams. The spacing of H-section steel columns has a significant influence on the total quantity of steel used and the total cost. We usually apply economic column distance of 6.8m to 9m, based on the normal load of the structures.
As for the projects with special needs, that can be flexibly adjusted. The determination of building height should not only meet the requirements of production equipment and production operations but also consider the height of maintenance more comprehensively.

2. Proper lighting and ventilation design

As the enterprises adopt intensive production, the characteristics of large-span and large-space internal spaces are becoming more and more apparent. Therefore, steel building design should pay attention to lighting and ventilation design from the perspective of humanization and energy saving. When the workshop building is tall, the openable window at the bottom of the side exterior wall is used as the primary air inlet. By installing a roof ventilator, the ventilation and lighting problems are easily solved, and the actual operation is relatively simple.

Difference between steel structure building and concrete building

1.Short construction period

In terms of the construction cycle, the steel structure has obvious advantages. The construction of the steel structure building is very fast because it is prefabricated in the factory and assembled on the construction site. Only slight weld works need be applied on site.

2. Environmental Friendly

After transported to the construction site, the steel components only need to be hoisted and spliced. The whole process can be operated without water. There is no flying sand and a large amount of dust, which can reduce environmental pollution and impact on nearby residents.

3. Favorable Cost

Steel structure buildings save construction period and labor costs compared with concrete buildings. The total cost of a steel structure building roughly is 20%~30% lower than that of traditional concrete building. What’s more, steel structure is more robust and more durable than concrete.

4. Structure Weight

The steel structure itself has the characteristics of lightweight. The walls and roofs of the steel structure are made of light metal building materials, which are much lighter than the brick-concrete wall and roof.
